š³ Poplar (Populus spp.) ā a wild medicine of late winter and early spring
Poplar treesāsuch as cottonwood and aspenāare best known for their resinous spring buds, which have a long history of use in herbal preparations like oils and salves. In late winter, these buds are already formed and quietly beginning to respond to longer days and shifting temperatures. As spring approaches, they become sticky and fragrant with resin, and the seasonal window for working with them is often brief.
Poplars belong to the same plant family as willow and share similar medicinal constituents, including salicylatesācompounds with a long tradition of use in herbal medicine for supporting the body through fever, pain, discomfort, and inflammation. These shared qualities are part of why poplar buds have been valued historically in topical herbal preparations such as balms and massage oils.
Keep an eye out to begin noticing and identifying poplar trees as the brief spring season for poplar buds approaches.
